either, side of the track. Near the ends of the timbers and on one sideof the track are parallel standards or supports 4 and 5, pivoted betweenwhich is a gate 6, adapted to be raised into a vertical position andwhich will be permitted to drop by gravity across the track to close thesame. Arranged on the ties to which the rails are secured a plurality ofstandards 7 are arranged in series on either side of the gate andcomprise each an approximately U- shaped casting having right-angularflanges 8 and 9 at its bottom edges, which are secured to the ties.Within each standard 7 is centrally pivoted a link rod or bar 10. Eachbar is arranged on a diagonal plane and at an opposite inclination tothe one preceding it, and one end of each bar is bifurcated, as at 11,to receive the end of the succeeding bar,

which is provided with an elongated slot 12' I to permit of a slightplay when pressure is applied thereto. These bars are also connected attheir upper ends to a longitudinallyarranged actuating-rail 13, whichmay receive pressure from a suitable throwing device on a locomotive orcar. When pressure is applied to the rail 13, all of the link-bars 10are actuated, thereby exerting pressure upon the gate-actuating lever14L, which is connected to one of the bars 10 at the end of the seriesof standards 7 said lever 14 terminating in a laterally-curved extension15, which is connected to a pivoted link 16, fastened or secured to thebatten 17 of the gate 6. On the opposite side of the gate a similarorganization of levers and actuating-bar is arranged, so that in theevent of a single-track system being employed the gate will be raised bythe train coming in either direction. In the raised position of the gatethe greatest weight is on the side of the fulcrum nearest the track, andas soon as the train has passed the gates will drop by gravity acrossthe track into the position shown in Fig. 1. As soon as the throwingdevice (not shown) which is carried by the train comes in contact withone of the rails 13 the gate will be raised and will remain in suchposition until the last car of the train passes the extremity of the baron the other side. It will be obvious that this can be accomplished byhaving the throwing device on the cars arranged so that they will be incontinuous contact with either of the bars 13.

In Figs. 7 to 9 I have illustrated the slightlymodified form foralternately closing the ence-numeral 23.) The reference-numeral 2 1'designates a transversely-arranged rock-shaft which extends beneath therails of the track and on the extremities of which arerightangularly-extending projections and 26. The end 25 of the shaft 24is connected to the batten of the gate 23 by a link connection 27. Theend 26 is connected by a similar link 28. When the gates 6 are down andacross the track, the right-angular ends 19 of the rockshaft 19 will bedepressed, throwing the arm 21 upward. This will cause one of the gates23 to be thrown up into a position indicated in Fig. 8 through themedium of the link 22. Inasmuch as the rock-shaft 24 is secured to thegate 23 opposite the arm 21 by a link connection, the same movement willbe imparted to the opposite gate through the medium of the shaft 24, thearm 26, and the link 28, so that both gates will rise simultaneously.The gates 6 are heavier than the gates 23 and will be weighted tocompensate for the friction of the mechanism for operating the gates 23,so that when the train or car has passed over the track the gates 6 willdrop by gravity across the same, thus closing the track on either sideof the street. As the gates 6 move toward the track motion will beimparted to the side or street gates through the medium of the mechanismindicated, thus raising them and opening up the street for traffic.

It will thus be seen that I have provided an efficient and durablemechanism for operating a gate or a plurality of them in a convenientand expeditious manner.

While I have specifically described what at this time I believe the Verybest means of accomplishing the desired result, I would have itunderstood that I do not limit myself to the exact details ofconstruction shown, but reserve the right to make such changes andalterations as will suggest themselves from time to time withoutdeparting from the spirit of this invention.

Having thus described the invention, what by Letters Patent, is

1. In a railway-gate, the combination with a transversely-arranged gatepivoted to be swung in a vertical plane, of a plurality of approximatelyinverted-U-shaped castings forming standards and arranged in seriesadjacent to the gate, inclined levers pivoted in the standards andconnected to each other and to the gate, and means for actuating thelevers simultaneously so as to raise or lower the gate.

2. In adevice of the character described, the combination with a gate,standards on either side of the gate to. which it is pivoted, aplurality of pivoted levers connected to the gate, each alternate leverbeing inclined at an opposite direction to the preceding one, and a railconnected to the levers and adapted to be operated upon so as to actuatethe levers to raise and lower the gate.

3. The combination with a gate, of a plurality of levers arrangedadjacent to the gate and inclined in opposite alternating series, saidlevers being connected to each other, a rail connecting the. levers soas to operate them simultaneously, an operating-lever at the end of thefirst-named levers, a link connection between the gate and theoperating-levers, whereby pressure upon the rail will tilt the gate.

41. In a railway-gate, the combination with a gate, of levers, eachlever having one of its ends bifurcated and the other end slotted, andmeans for connecting the inmost lever to the gate, and means forconnecting the levers and adapted to be operated upon so as to actuatethe levers to operate the gate.

5. In arailway-gate, the combination with a gate, means for operatingsaid gate, gates arranged at angles to the first-named gate, a shaft,links connecting the shaft to the last-named gates to permit theoperation of one gate to operate the other, another shaft, linksconnecting the last -named shaft to the first-named gate and one of thelast-named gates, whereby the opening of the first-named gate will closethe last-named gates and the closing of the firstnamed gate will openthe last-named gates.

6. In a railway-gate, the combination with a gate, of levers, each leverhaving one of its ends bifurcated and the other end slotted, means forconnecting the inmost lever to the gate, means for connecting the leversand adapted to be operated upon to actuate the levers to operate thegate, gates arranged at angles to the first-named gate, a shaft, linksconnecting the shaft to the last-named gates to permit the operation ofone gate to operate the other, another shaft, links connecting thelast-named shaft to the first-named gate and one of the last-namedgates, whereby the opening of the first-named gate will close thelastnamed gates, and the closing of the first-named gate will close thelast-named gates.

7 Ina railway-gate, the combination with a gate, of levers, eachalternate lever being inclined in an opposite direction to the onepreceding it, means for connecting the inmost lever to the gate,meansfor actuating the levers to operate the gate, gates arranged at anglesto the first-named gate, a shaft provided with an arm, a link connectingthe shaft to the firstnamed gate, a link connecting the arm to one ofthe last-mentioned gates, a shaft provided with arms, and linksconnecting the last-named arms to the last-named gates.

In testimony whereof I aflix my signature in presence of two wltnesses.
